Lucid Autowerks Ultimate Manual Tire Changer: What the Attachment Is and What It Needs

Lucid Autowerks sells a branded duck-head conversion for imported floor-post changers. This page describes the product from the maker's own shop pages and instructions, read on October 11, 2026. We have run no trials with it, we could not read its warranty terms, and we earn nothing when you buy it from the maker.

Short verdict

The attachment is well documented by its maker, which publishes parts lists, the required post size and step-by-step instructions. Two things stay open. Its wheel size claim goes well beyond what the manual of the machine underneath allows, and that manual does not provide for third-party parts at all. When we read the shop pages, both main versions were shown as sold out.

What you get, by version

All entries follow the maker's product pages. The maker adds that paint may have to be removed from the post cap for the DELUXE to fit, and that the duck head may differ from the photos. The cone is stated for hub openings up to 2.9 in. on the product pages; the instructions give 64 mm for the same part. Measure your wheel's center hole and ask the maker if it lies between the two figures. The shop also lists single parts, among them a center guide, duck-head flanges in two styles and a billet aluminum centering cone.

What it changes on the machine

A floor-post changer in stock form levers the bead over the rim with the flattened tip of a steel bar. The attachment puts a duck head on an arm that pivots on the post cap. According to the instructions, the head is set to ride just above the rim lip, the bead is lifted over it with a tire iron, and the changer's own bar then pushes the arm around the wheel. For mounting, the maker notes that a rim clamp may be needed to keep the outside bead in the drop center; why that channel matters is explained under how to mount a tire on a rim.

The instructions also say to attach the changer securely to a solid, level surface and recommend drilling a hole in that surface so that a lug bolt and nut can hold the wheel. The maker presents this as a way to prevent damage to the wheel. On this site the wording for every manual tool is narrower: a duck head and a held wheel reduce steel-on-rim contact; marks remain possible.

Three limits to know before you order

• The machine underneath. The reference changer of this design, Harbor Freight item 58731, excludes standard tires over 16 in. and warns against use on high-end rims, according to the copy of the owner's manual on ManualsLib. An attachment does not change the post, the base or the bead breaker.
• The manual's rule on accessories. The same manual says to use the changer only with the accessories included and not to modify it. The attachment is outside what the manual covers; using it is your own decision.
• Low-profile tires. The tire makers say to use only equipment that is designed to accommodate low aspect ratio, high performance tires and wheels. The maker's figure of wheels up to 22 in. is a maker's claim about clearance, not a statement from the tire industry. See can a manual tire changer do low-profile tires.

Seating the beads afterward follows the same rule on any machine: never more than 40 psi to seat beads, and if they are not seated at 40 psi, deflate completely, reposition the tire on the rim, relubricate and reinflate.

The EXODIOS kit^* (paid link) is the budget choice for changers of other brands, and the Krysolad kit^* (paid link) is listed with a bearing, which is the feature that separates the Lucid DELUXE from the LITE. Both are known to us from their listings only: fit and the listed 16 to 21 in. range are seller statements, and the limits of the machine underneath apply to them in the same way. All kits are compared under duck-head kits for manual tire changers.

What else can be added to a floor-post changer, and what the manual says about it, is on the page about manual tire changer upgrades. The machine itself is described under Harbor Freight tire changer, and stated sizes of all changers are collected under rim sizes.
